public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

Answer
You maybe having this error on your java files because there is one or more XML file with error.
Go through all your XML files and resolve errors, then clean or rebuild project from build menu
Start with your most recent edited XML file
